The use of water splitting has been investigated as a good alternate for storing electrical energy. While the general interest in developing non-toxic, high-performance, and economically feasible catalysts oxygen evolution reaction (OER) is noteworthy, there also significant research. Recently, perovskite-type oxides have performed an alternative to non-precious metal can act new class effectiv...

Ilmenite is a valuable industrial mineral containing Fe and Ti elements. Two composites with different morphology and composition were produced using the reaction of synthesized ilmenite and aluminum. The molar ratios of 1:2 and 1:8 were selected. The critical temperatures of each molar ratio were determined using the Differential Thermal Analysis (DTA). The heat treatment of the systems ...

Ilmenite (FeTiO3) is a suitable mineral to produce titanium dioxide (TiO2) for photocatalyst applications. Therefore, this research was conducted synthesize TiO2 material from oxysulfate (TiOSO4) extracted Indonesia local ilmenite and modify into nanotubes through hydrothermal process at 150 °C 24 hours followed by post-hydrothermal treatment with temperature variations of 80,100, 120, 12 hours...

This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...

In this article we review and discuss a mechanism for coupling between electric polarization and magnetization that can ultimately lead to electric-field switchable magnetization. The basic idea is that a ferroelectric distortion in an antiferromagnetic material can “switch on” the Dzyaloshinskii-Moriya interaction which leads to a canting of the antiferromagnetic sublattice magnetizations, and...

In this paper we present an analysis of the magnetic toroidal moment and its relation to the various structural modes in R3c-distorted perovskites with magnetic cations on either the perovskite A or B site. We evaluate the toroidal moment in the limit of localized magnetic moments and show that the full magnetic symmetry can be taken into account by considering small induced magnetic moments on...

Ilmenite (FeTiO3) is an important mineral, formed in igneous and metamorphic rocks, and is the main feedstock for the titanium industry. Ilmenite is also an attractive and inexpensive oxygen carrier for chemical-looping combustion (CLC), one of the most promising technologies to accomplish CO2 capture in power plants [1]. The technique uses solid metal oxides as an oxygen carrier, which transfe...
